I have a table called tblProducts. It contains these fields as below:
ItemID
ItemAltID
ItemDescription
Brand
Unit
MarketPrice
CatergoryID
PAcctID

I have another table called tblStockReceivedDetails. Inside the table, it contain following fields as below:
SRID
SRItemID
SRItemAltID
SRItemDescription
SRBrand
SRUnit
SRMarketPrice
SRCatergoryID
SRPAcctID

I am using Visual Web Developer (VWD) with access database. Here is the situation. I have a webpage called StockReceived. This is the page where my user is going to do a stock received every time when their stocks come in.

So everytime, when there are new stocks, they will click a "Add Items" button, it will pop out a mini webpage & contains all the product from the "tblProducts". The user will then check a checkbox beside if that is the particular stocks to be received. Until here, I can still able to do it by using a gridview with ItemTemplate (For the checkbox).

Now, from here, I do not know how to go about as I am still a newbie in Asp.net.
How to I based on the checkbox, transfer selected data from tblProducts to tblStockReceivedDetail below is the codes I have created for my 2 tables.

Someone kind enough to advice me. I am struck....
